To all whom it may concern:

Be it known that I, JENS WULrr, a'citizen of the United States, residing at Erwin,

,bhihe. a

The head 8 is loosely retainedwithin the in the county of Kingsbury and State of South Dakota, have invented new and useful Improvements in Flying-Machines, of which the following is a specification.

This invention relates to ing machines,

and particularly to means 1 or controlling the longitudinal and lateral balance thereof, the object of the invention being to provide simple and effective controlling mechanism for automatically maintaining the longitudinal and lateral equilibrium. f

The invention consists of the features of construction, combination" and arrangeme t of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which gure l is a vertical longitudinal section Fi through a' flying machine embodying my invention. Fig. 2 is a vertical transverse section of the. same. Fig.- 3 is a top plan view of the balancing pendulum and its support.

Fig. 4 is a sectional elevation of the same,

Fig. 5 is a detail view of one of the T- shaped'levers' for operating the lateral balanci planes. t

Re rring to the drawin s, 1 designates a flying machine of an of. t e types-in common use, which mac ine'is provided with front and rear horizontal rudders 2 and 3 for controlling the longitudinal balance thereof, and balancing planes or equivalent devices 4 and'5 for controlling the lateral equilibrium thereof.

Arranged-at a suitable "u on the machine s a bracket; or suppbrfin member 6 provided with a band bor .partia ly spherical socket 7 receiving a all or head 8 upon a gravitycontrolled balancing element or pendulum 9 having an upwardly extending arm IQ and a de ending arm 11, the latter carrying a weight 12 for maintaining said pendulum in a perpendicular position irrespeetive of the tilting-motions of-the maband or collar 7, so as "to have universal motion, so that upon the tilting of the vessel on either oiits axes a relative balancing motion between the machine and the pendulum will be established for controlling the balancing planes ordevices.

'As shown, connections in the form of wires or cables 13 and 14 lead from the upper and -lower arms of the pendulum to the frontand rear balancing planes or rudders 2 and3, while similar connections 15 and 16 leadfrom the upper-andlower arms of the pendulum .to the balancing planes 'or devices4 and 5, the construction and arrangem'entbeing such that when the machine tilts in a; fore and aft direction the rudders 2 and 3 will be tilted in opposite-directions to restore the longitudinal-balance, while, when the machine tilts laterally in either direction, the balancing planes or devices 4 and 5 will be properly adjusted in opposite directions to restore thelateral balance. The connections 15 and- 16 are-attached at their outer ends to the upwardly and downwardly extending arms17 and 18 of T-shaped levers .19, fulcrumed at the points of intersections of their arms to brackets 20 on frame pieces21 for swinging movement in. a vertical plane. The outwardly projecting horizontal arms 22 of said levers are provided with longitudinal slots 23 which re'- ceive and slidablyand 'pivotally engage the inner end bar 24 of the frames of the balancing planes 4 and 5, in advance .of the pivotal points ofv the latter, said planes bee. mg slotted, as at 25, to permit free movement of said arms 22. Hence when the connections 15' and 16 are operated one of the levers 19 will be swung downward and the i other upward to correspondingly adjust said balancing. planes- 4 and- 5, asywill be readily understood. It will thus 'be seen that the, invention provides simple'an'd effective means -for maintainirig both the longitudinal'and later-a1 equilibrlum of the maehine,,and it will be understood that the endulum\may alsobe employed as a lever or manual operation whereby the setsof balancing planes or devices are also placed; under the complete control of the, aviator,

Having thus described the invention, what I claim 'as new is:

A flying machine embodying a frame, pivotally: mounted balancing planes formed with slots and having inner end bars, T- shaped levers pivotally mounted upon the frame adjacent to said balancing planes and provided with vertical arms and horizontal arms, the horizontal arms being slot-ted and slidably and pivotally engaging the said inner end bars of the balancing planes and freely movable through the slots therein, connections between the vertical arms of the levers, and a controlling pendulum coupled m to said connections.

In testimony whereof I afiix my signature in presence of two witnesses.
